5. You are using too much heat
Length retention has a huge mechanical component to it. Heat ultimately degrades hair. For some people, regular heat use is not a problem as their hair is able to cope, but for others, even slight heat is an issue. The finer and kinkier your natural hair, the less likely it is to tolerate a lot of heat. Learn how your hair reacts and don’t choose style or ease above hair health. Also, consider heat-free methods such as curl formers, braids, twists or banding.
